1. A control system for a vehicle power seat (1), said system comprising at least an electric actuator (27, 44, 56) for powering one seat movement, and control means (80, 80'"'"', 80") for controlling operation of the same;
- an electronic control system (70) for detecting operation of said control means (80, 80'"'"', 80") and for electrically connecting a power supply to said actuator (27, 44,
56) over supply wires (77, 77'"'"') which, when said actuator (27, 44,
56) is idle, cuts off from the said power supply;
said electronic control system (70) includes a first means (94) for detecting operation of said control means (80, 80'"'"', 80") via a variation in an electric input signa;
said first means (94) determining, via a second means (103,
112), a status of the means (83) for electrically connecting the power supply to said actuator (27, 44,
56) over said supply wires (77, 77'"'"'); and
said second means including a relay (112) for establishing the status of the means for electrically connecting said power supply to said actuator (27, 44,
56) over said supply wires (77, 77'"'"').

Abstract
A control system for a vehicle power seat, which includes at least an electric actuator for powering at least one seat movement and a controller for operating the same. The system includes an electronic control system for detecting operation of the aforementioned controller and connecting the actuator to an electric power supply over wires which, when the actuator is idle, are cut off from the power supply.
